Synchronizing with Thunderbird

Synchronize your mail.com
Organizer with your calendar application on Thunderbird to make sure,
that your appointments are up to date.

If you use the "Lightning" add-on for Thunderbird, you can configure
automatic synchronization. Due to the technical limitations of Thunderbird, you
have to synchronize each of your calendars (default calendar and other
calendars) individually.

How to configure automatic synchronization of your
mail.com default calendar with Mozilla
Thunderbird

Note:

Thunderbird does not include its own calendar. In
these instructions, we use the free Lightning add-on on a PC with Windows 7.
